Fetch account balances

Intermediate

Tutorial

This endpoint allows you to fetch the balances for a certain account. It is the implementation of the /account/balance endpoint of the Rosetta API standard.

Prerequisites

• Your Rosetta instance is up and running under the address 0.0.0.0:8081.

  Make sure to use the correct NetworkIdentifier as described in this section. For this example an arbitrary AccountIdentifier 8b84c3a3529d02a9decb5b1a27e7c8d886e17e07ea0a538269697ef09c2a27b4 was used.

Example

curl --location '0.0.0.0:8081/account/balance'  --header 'Content-Type: application/json' --data '{
    "network_identifier": {
        "blockchain":"Internet Computer",
        "network":"00000000000000020101"
    },
    "account_identifier": {
        "address": "8b84c3a3529d02a9decb5b1a27e7c8d886e17e07ea0a538269697ef09c2a27b4"
    }
}'

The response will give you the balance of the AccountIdentifier at the most recent block.

{
    "block_identifier": {
        "index": 9890652,
        "hash": "30217e980397e9a8e14793563511e2d3191aa2df6d623866fa71f967e2ce3f08"
    },
    "balances": [
        {
            "value": "62841206500025",
            "currency": {
                "symbol": "ICP",
                "decimals": 8
            }
        }
    ]
}

If you want to know the balance of a staked neuron, you can specify the account type. You need to make sure the account_identifier you specify corresponds to the ledger address of a neuron. Set account_type to neuron in the request metadata to tell the Rosetta node that you want to get the account for staking. The neuron_index parameter is an arbitrary 64-bit unsigned integer that the caller chooses to identify the neuron. A single user can control multiple neurons and differentiate them by specifying different values of neuron_index. neuron_index is optional and is equal to 0 by default.

curl --location '0.0.0.0:8081/account/balance'  --header 'Content-Type: application/json' --data '{
    "network_identifier": {
        "blockchain":"Internet Computer",
        "network":"00000000000000020101"
    },
  "account_identifier": {
    "address": "a4ac33c6a25a102756e3aac64fe9d3267dbef25392d031cfb3d2185dba93b4c4"
  },
